Edit array_diff_key code | JsPHP: a JavaScript library providing the PHP API

Edit: array_diff_key

Function:

Description:

Returns the entries of arr1 that have keys which are not present in any of the others arguments. This function is like array_diff() but works on the keys instead of the values. The associativity is preserved.
